The primary aim of the present study was to explore the heterogeneity of emergent literacy skills among preschool-age children with specific language impairment (SLI) through examination of profiles of performance. Fifty-nine children with SLI were assessed on a battery of emergent literacy skills (i.e., alphabet knowledge, print concepts, emergent writing, rhyme awareness) and oral language skills (i.e., receptive/expressive vocabulary and grammar). Cluster analysis techniques identified three emergent literacy profiles: (1) Highest Emergent Literacy, Strength in Alphabet Knowledge; (2) Average Emergent Literacy, Strength in Print Concepts; and (3) Lowest Emergent Literacy across Skills. After taking into account the contribution of child age, receptive and expressive language skills made a small contribution to the prediction of profile membership. The present findings, which may be characterized as exploratory given the relatively modest sample size, suggest that preschool-age children with SLI display substantial individual differences with regard to their emergent literacy skills and that these differences cannot be fully determined by children's age or oral language performance. Replication of the present findings with a larger sample of children is needed.
本研究的主要目的是通过对表现概况的考察,探究患有特定语言障碍(SLI)的学龄前儿童在早期读写技能方面的异质性。对59名患有SLI的儿童进行了一系列早期读写技能(即字母知识、印刷概念、早期书写、韵律意识)和口语技能(即接受性/表达性词汇和语法)的评估。聚类分析技术确定了三种早期读写概况:(1)最高早期读写能力,字母知识优势;(2)中等早期读写能力,印刷概念优势;(3)各项技能最低早期读写能力。在考虑儿童年龄的影响后,接受性和表达性语言技能对概况归属预测的贡献较小。鉴于样本量相对较小,本研究结果可被视为探索性的,表明患有SLI的学龄前儿童在早期读写技能方面存在显著的个体差异,且这些差异不能完全由儿童的年龄或口语表现来确定。需要对更多儿童样本重复本研究结果。
